INFO

In order to setup and use Datameer X for your purposes, the following prerequisites must be fulfilled.

Datameer X Application Server Requirements

Minimum Recommended Hardware for the Production Environment with a Database on the Same Server as Datameer X:

1U Server
2 Quad Core CPUs
16 + GB RAM
2 x 1 TB Hard Drives (Recommended available disk space: 250 GB)
RAID - 0 striping
RAID - 1 mirroring
Dual 1GbE network
Redundant power
Failover requires a standby server with the same configuration

Required Software:

Datameer X is a Java application and requires an operating system that supports Java Runtime Environment:

UNIX/ LINUX operating system
MySQL 5.5 or MariaDB 8 and higher
Java Runtime Environment (JRE) version 8+ current minor version
INFO

Limit: Currently, the JRE version 12+ is not supported with Datameer X.
Installed software: SSH, VI, GNU sed, MySQL 5.5 or higher (server and client executables must be available via shell search path)
MySQL Database

Datameer strongly recommends using MySQL databases. Datameer service depends on the MySQL database, and it is used for constant writes for workbooks, permission changes, job execution, and scheduling, among other things. For proper function, a response time should be between ten and twenty milliseconds.
Optional: SMTP server (for email notification)

Datameer X Database Server

The Datameer X database should be hosted on the same machine as the Datameer X application server. It can be located on a hosted database only if the response time for a full write to the database is less than 20 milliseconds. If during database maintenance the database response can't be guaranteed, you need to gracefully shut down the Datameer X service before maintenance.

Hosted databases must use MySQL 5.5 or higher, the recommended size is a minimum of 5 GB
MariaDB version 8+ is supported as an alternative to MySQL

Cluster Requirements

Managed Cloud Cluster Platforms

Datameer X is supporting recent versions of the managed fully-elastic cloud cluster platform Amazon EMR, Azure HDI as well as Google DataProc. For more details review supported Hadoop Distributions.

Hadoop Cluster

One of the supported Hadoop Distributions is installed
Gigabit switches (10 GigE interconnected)
Sufficient power supply & cooling

The vendor of the Hadoop distribution being used should be available to provide the Hadoop cluster design and sizing recommendations.

Info

Ensure that the installed JRE on Datameer X Server and all Hadoop compute nodes are exactly the same.
